On my trip back across Kachemak Bay two days ago, I saw some big splashes head of me as I piloted Skookum home from a day of charter fishing.

It was two humpback whales fishing together and fluke-slapping the surface of the water to signal one another. After sounding (deep dive), the whales breached the surface, coming more than two-thirds out of the water, spinning and crashing back down.

Whale biologists hypothesize that this is a feeding technique in which the whale stuns schools of small fish they're feeding on. Whatever the reason, it's an amazing show!
